4. Emergency operation
If remote controller or microcomputer fails but there is no other trouble, emergency operation is possible by setting dip switch [SW3<I. B>] on the indoor controller board.
[Check items]
(1) Compressor and fan.
(2) Check the trouble position using self diagnostic function. If the result of self diagnosis indicates protective device such as freeze protection is functioning emergency operation is not possible unless the cause is removed.
(3) In emergency operation, the operation made by only ON / OFF circuit breaker manually [ON / OFF with remote controller is not possible].
[Emergency operation procedure]
(1) Cooling is possible by setting 1 . 2 ON and 3 OFF for the dip switch (SW3<I.B>) at indoor controller board.
(2) Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker in this order.
(3) During emergency operation indoor fan runs at high.
(4) Thermostat will not function.
(5) Do not cooling for more than 10 hours (the indoor unit heat exchanger can freeze).

To prevent overload, the compressor will not start within 3 minutes after stop.
2 The compressor runs when the room temperature is higher than the set temperature.
The compressor stops when the room temperature is equal to or lower than the set temperature.
3 The compressor stops in check mode or during protective functions.
4 Coil frost prevention
To prevent indoor coil frost, the compressor will stop when the indoor coil thermistor (RT2) reads 1°C or below after the compressor has been continuously operated for 16 minutes or more. The coil frost prevention is released under any of the following conditions.
● The indoor coil thermistor rises to 10°C or above.
● The room temperature becomes equal to or lower than the set temperature.
● COOL mode is stopped or changed to another mode.
NOTE : By cutting the jumper wire JRO2 on the indoor controller board, the temperature to start coil frost prevention changes
from 1°C to -3°C.
5 Coil frost protection
When indoor coil temperature becomes -15°C or below, coil frost protection will proceed as follows.
<Start condition>
After the compressor has been continuously operated for 3 minutes or more, and the indoor coil temperature has been
-15°C or below for 3 minutes, the coil frost protection will start.
<Coil frost protection>
Compressor stops for 6 minutes, and then restarts.
lf the start condition is satisfied again during the first 10 minutes of compressor operation, both the indoor and outdoor
units stop, and the remote controller displays this occurrence.
<Termination conditions>
Coil frost protection is released when the start condition is not satisfied again during the allowance, or when the COOL
mode stops or changes to another mode.

(2) Indoor fan control
Indoor fan speed LOW/HIGH depends on the remote controller setting.
However, if an outdoor unit abnormality is detected, the indoor fan speed will be LOW, regardless of the remote controller
setting.
(3) Detecting abnormalities in the outdoor unit
After the compressor has been continuously operated for 3 minutes, if the difference between the difference between the
indoor coil temperature and room temperature is out of RANGE C, for 1 minute, the indoor fan speed will turn to LOW. Five
minutes later, if the difference is in RANGE C, the fan speed will return to the set speed. If the difference is still out of RANGE
C, the outdoor unit is deemed abnormal.
Thus, the compressor will stop and the trouble location is indicated on the remote controller.
RANGE A : Indoor coil temperature is more than 5 degrees above room temperature.
RANGE B : Indoor coil temperature is within 5 degrees either way of room temperature.
RANGE C : Indoor coil temperature is more than 5 degrees below room temperature.

4 The compressor will not start when the room temperature is below 18°C.
The compressor starts intermittent operation when the power is turned ON with room temperature above 18°C. The compressor ON / OFF time depends on the thermostat ON / OFF and the room temperature as follows.
After 3 minute compressor operation,
● If the room temperature thermistor reads above 28°C with thermostat ON, the compressor will operate for 6 more minutes
and then stop for 3 minutes.
● If the room temperature thermistor reads 26 °C ~28 °C with thermostat ON, the compressor will operate for 4 more minutes
and then stop for 3 minutes.
● If the room temperature thermistor reads 24°C ~26°C with thermostat ON, the compressor will operate for 2 more minutes
and then stop for 3 minutes.
● If the room temperature thermistor reads below 24°C with thermostat ON, the compressor will stop for 3 minutes.
● If the thermostat is OFF, regardless of room temperature, the compressor will stop for 10minutes.
5 Coil frost protection
Coil frost protection in DRY operation is the same as in COOL operation.
(2) Indoor fan control
The indoor fan runs on LOW speed during compressor operation. The fan speed cannot be changed with the remote controller.
Also, the indoor fan does not run during compressor OFF.
(3) Detecting abnormalities in the outdoor unit
An abnormality in the outdoor unit can not be detected in DRY operation.

on the remote controller. All the other lamps are OFF
normally.
@ To activate the self-diagnostic function for service,
press the UP and DOWN buttons simultaneously for
more than two
TEMP
seconds during operation with
lamp ON
# The timer lamps show the latest trouble. Trouble data
is memorized until the next trouble occurs, even when
the breaker turns OFF.
$ All buttons except the POWER ON/OFF are unavailable during the self-diagnostic mode.
% To release the self-diagnostic mode, press the
POWER ON /OFF button.
2-7 Emergency operation
When the remote controller or microprocessor malfunctions and no other trouble exists, emergency cooling
operation is available by setting the dip switch on the
indoor controller board.
[Check items]
! Make sure the compressor and the fans are running
normally.
@ Locate the trouble with the self-diagnostic function. If
the self-diagnostic function indicates that the protection device (such as coil frost protection) is functioning,
the sources must be removed before attempting emergency operation.

2-8 Function of jumper wire and dip switch on indoor controller board
1. Jumper wire
1 JR1...Jumper wire for the auto vanes.
Cut JR01 for the unit WITHOUT auto vanes.
2 JR2...Jumper wire for the temperature to start coil frost prevention
Cutting JR02 changes the temperature from +1°C to -3°C.
3 JR3...Jumper wire for set temperature adjustment in HEAT mode.
In HEAT operation, heated air stagnates in the upper part of the room. The indoor unit installed in the upper part of the
room will detect the air temperature higher than the actual temperature in the living space. This difference is about 4
degrees. Therefore, the temperature detected by the room temperature thermistor should be corrected 4 degrees down.
The unit with JR04 attached will make this adjustment.
4 JR4...Jumper wire for the indoor fan speed during thermostat OFF in HEAT mode
Cutting JR04 changes the speed from Extra-Low to Low.
5 JR5...Jumper wire for detecting abnormalities in the outdoor unit
Cutting JR05 makes this detection unavailable. (Occurrence of abnormality can not be detected. )
6 JR6...Jumper wire for auto restart function
Cutting JR06 makes the auto restart function available.

Note 1. How to connect refrigerant pipes.
Factory supplied optional refrigerant piping contains refrigerant at the above atmospheric pressure. As long as connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor
units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 20m, an additional charge of refrigerant is needed.
Note 2. The following main parts are contained in the optional refrigerant piping kit.
Heat insulating cover, vinyl tapes, nipples, sleeve, flange (for wall hole).
2. REMOTE CONTROLLER EXTENSION CABLE
When installing the remote controller at a distance from the air conditioner, use the designated extension cable with connector.

3-2 Feature of program timer
(1) Daily timer function
Daily timer can be set in 30 minute units up to 24 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.
(2) Setback operation. (PAC-SK65PT)
Set back operation is useful for reducing running costs
e.g. : At a hotel with a 24-hour system
8:00~23:00 Cooling operation with set temperature at 26°C
23:00~8:00 Setback operation with 2 degrees of setback
As shown in the chart on the right, the set temperature rises 2
degrees automatically during the setback operation. When the setback operation ends, normal operation will begin.
(3) Weekly timer function
Daily timer function can apply to each day of the week.

(2) Set the address number (from SW1-1 to SW1-6) in
the dip switch when a centralized remote controller is
being used.
The address is the control number of each unit in the
centralized control system.
As the address serves as a time-delay device as
well, sequential starts (all units are triggered collectively by one single ON instruction)must be set with
different address numbers (greater than 0) for each
adapter.
